' Application an September 14, 1904. Serial in. 224,457.

To all whom it may concern: Be it known that I, ALBERT O. MENGES, asubstantially disk-shaped and is provided -citizen of the United States,residing at centrally thereof with an upwardlyroject- Grand Rapids, inthe county of Kent and j ing cylindrical extension 2, and, rther- 5.State of Michigan, have invented new and 1 more, provided with a cap 1.Within the cylindrical extension 2 is arranged an, actuating-spring 7,and said extension 2 has also arranged therein the valve-stem 5. The cap1 is what may be indicated by the reference character 8, so as toreceive and retain the upper end of the spring 7. i 3 The referencecharact'er i denotes the valve, which is secured to thelower end of thestem and finds its seat against the lower face of the'lower' section 3.A bearing 6'is provided for the'valve-stem 5. v

The compression-sprin ,at one end against the-dis Explosion-Engines, ofwhich the following is a specification. p

his invention relates to certain new and useful improvements inintake-valves for explosive-engines; and the invention consists in thecombination and arrangement of parts hereinafter described and claimed;-I

The objects of the invention are, first, to produce a valve for anexplosive-engine which will furnish the required amount of explo- 'sivecharge to correspond withthe amount of work to be accomplished by theengine; sec-' v0nd, to produce a valve which will furnisha" minimumamount. of explosive charge, so that the engine may be continued inoperation without roducing any other work;

3 third, to furnish a valve whereby the tension on the spring whichcontrols the valve may 7 finds a bearin -shaped portion 0 the section 2and at its upper end a ainst the cap 1, and said s ring 7 is adapte toautomatically close the valve 4 and move the same to its seat after ithas been drawn away by the ingoing charge. The upper portion of thelower section '3 is, substantially diskshaped and has de lar extensionof a diameter nearly as large as the disk-shaped portion of said section3 The disk-shaped portions of each of the sections 2 3 are provided withports 9, which are adapted to register with each other, and the saiddisk-shaped portion of the lower section is provided with the orts 10,which are adapted to register wit the cut-away portions 12, formedin'thedisk-shaped ortion of the upper section, for the purpose afterdescribed. The cut-awayporti have one wall thereof beveled. The lowersection 3 is provided'with upwardly-extendin projections 11, which are won the upper section 2 is rotated the bevsame time, so that the valvewill. act quickly,

. and thereby increase the s eed of the en ine.

These, objects I accomplis by means 0 the mechanism illustrated in theaccompanying 0' drawings, in which- Figure 1 shows a plan view of thevalve detached from the engine, showing the position of the ports whenthey are all 0 en and the valve-has its maximum amount 0 throw.

3 5 Fig. 2 is a cross-section of the'valve on the line w 00 of Fig. 1,showing the osition of the valve-stem, the spring, and t e ports whenopen. Fi 3 shows a side elevation illustrating the va ve adjusted sothat it hason'lya o slight throw. Fig. i is an inverted lan view of theupper valvecas e, which is in mated by 2 in the drawings. 1

Like numerals refer to'like parts throughout the 'several'views.

11. These at oneslde the upper easily ride over the projectwns cut-awayportions or openin s 12 are practically at htang esto section 2, asshown y 12, and, are wed eshape d on the other side, so that when t eupper section 2is turned itjwiiLbe raised away from the lower section3,'thereby com ressing the spring, thebeveled-portmns beingshownby 14.

the valve is formed of what may be termed two* sections, an upper and alower section. Said u per section is indicated by the reference 0'aracter 2 and is rotatablefand said lower sectionis-indicated by the;reference charac- .-,ter"3}and ,-.is -secured to the engine+cylind r,

, t m. I

l The upper section 2 at its lower portion is termed cup-shaped, as

eremons 12 V ending therefrom a tubu beveled, so that- I eled wall ofthe cut-away portions12 can 29 with the f r turned the upper-section 2is raised, thereby 13 is an opening in the upper section showingabearing for the projection 6. This opening 13 is shown in Fig. 4, andthe-hearing-fi is shownin Fig. 2.

15 is a pin or other suitable-.nieans for securing the cap 1 in placeupon the valvestem 5. j i

The arrows 15 and 16 merely show directions for turning the section 2for the pur 1o poses of opening and closin the ports.

' In Fig. 1 the valve is shown with all the ports open in position forthe engine to run at 0 its full power. This figure also shows the po--sition when the cap is raised, so as to give the 15 valve its maximumthrow and the-freepassage of the ex losive charge into the engine. Byturning the section 2 in the direction shown by the arrow 15. thebeveled portions 14 of the openings 12' are brought in contactprojections 11, and as the same is shortening the stroke gradually ofthe valve and valve-stem. This may be continued'until the stroke isreduced to a minimum. The object of this is to prevent the engine-fromrattling when the power required for running it is shut off or partiallyshutofl, and it-may V be turned to such an extent that the engine 'willmove without outside machinery. v I

- Starting with the valve in the position shown in Figs. 1 and 2, allthe ports are open; but the upper section 2 maybe turned backward in thedirection shown by the arrow 16 until it will practically close theports 9 9 9 andwill decrease the openings 10 to such an ,extent that buta small quantity of explosive charge. may be taken through them into.the en e, leaving, however, the piston and 4,0 va ve in position to havethe maximum 5 throw. Thus the structure'is such that the valve may beadjusted to its throw with the ports open and to its maximum throw yviththe ports nearly closed, or to any intermediate position between thetwo, thus enabling me to adjust the amount of the inoingcharge to the reuired work to be perormed by the engine om'the point where the enginewill run without producing an 5 outside powerto the position where it wiI- produce the maximum amount of power, and inasmuch as the openings andclosings are governed by the inclined or cam-shaped suraces the valvecan be adjusted with great accuracy and precision. Thus the valve can bethrottled without interfering with the throw of the valve and can beregulated so as to take on more or less of the explosive charge withoutinterfering with the throw of the valve. The same also may be adjustedso as to increase the explosive charge by turning the upper section andat the same time shortening the throw of the valve;

conveying any power to In Fig. 4 of the drawings a conventional means isshown for adjusting the upper section and for retaining said uppersection in its adjusted position, said means consisting of a rod 16,extending down through a casing 17 and having a forked lower end 18extending between a air of stop-pins 19. The rod 16 carries a hand wheel20 and is also screw-threaded, as at 21, and with the saidscrew-threaded portion 21 a jam-nut 22 engages, which when rotated inone direction will fix the rod 16 to thecasing 17. It will be evidentthat when the nut 22 is loosened the rod 16 can be turned to shift theupper section to-the desired position, and after said section is ad--vjusted the screwing home of the nut 22 will prevent the rod 16 frommovement, thereby retaining the upper section in its adjusted position.By this means the tension of the spring is increased, which gives a morerapid motion to the valve, and consequently a more rapid motion to theengine.

Having thus described my'invention, what I claim to have invented, anddesire to secure by Letters Patent, is

1. In a valve for explosive-engines, the combination of the valve andvalve-stem, a casing formed of a lower section and an upper sectionrotatable thereon, the lower section provided with beveled projectionsand the uppersection with openings having inclined sides adapted toengage with the projections as the upper section is rotatedfor thepurpose of lengthening or shortening the throw 'of the valve.

2. The combination in a valve for explosive-engines, of a casing formedof an upper and a lower section, the lower of which is secured to theengjipe and provided with ports,

the upper of w ch is secured to the lower section and provided withports adapted to register with the ports of the lower section, a seriesof projections upon the lower section, said upper section having'aplurality of openings provided with inclined or wedge-shaped si esadapted'to engage with the projections 'on the lower section when the,upper section is turned, whereby the upper section may be raised andlowered for. the purpose of shortening or lengthening the throw of thevalve, a spring adapted to automatically close the valve and a cap onthe stem for retaining said spring in position.
